A ball valve 19 is arran ed for limited and is formed of rubber, porcelain, brass or other desirable material being adapted for assistance .in seating by reason of its own weight. A middle Section 12 is threaded to the upper section 11 of the plunger 43, having e bolt slidably arranged therethrough axially of the" plunger :and C rovided -with a squared head 47 arrange' within vthe rectangular chamber 16 in the bottom of'the section 11 while a packing 17 is interposed between the head 47 and the upper end of the chamber 16.

A lower section v13 is secured beneath the section 12 and a packing 18 is also secured there-between by means of n. screw 15 threaded into the lower end of the bolt 18, a conceved face 48 being provided in the lower end of thesection 13 adapted for engaiing the ball 19. n apron :2.2` in dependingr flange, is externally. threaded upon the upper oxrim portion49 ofthe casing cup 40. and is provided with on annular washer or packmg24 seated within the inner face thereof, an ,annuler charnber 26 being thereby provided. between the pecking 24 and the outer face of the cu 440. Any desired number of perforations 7, 7* are Aprovided through the cup 'l0-for outletting the water therefrom, the water thereafter entering the tank from -the valve through the annularoutlet 27 at the bottom of the chamber 26. A laterally projecting lug 23 is carried by the apron 22 having a. passage therethrough connecting with the cham er'26 being adapted for-.the mounting of a rell pipe 25 when the valve is employed in a low form of tank.

The operation of the device will be apparent from this description thereof, the opening and closing of the valve seat passage 41 being controlled by the ball valve 19 and the float operated plunger 43, the water passing through intake and the scat 2 entere the 'casing chamber 21 by passing around and through the cage 20. l The outlet ports 7 and 7, unitedly 'provide a eater diameter for the out-ilo .water m the the .-forrn of an annular.

ted between metallic bodies by the interposing of the washer' 1B and 'the employment of the packing 17. The bottom section 13 is normallyslightly spaced from -the section 12 a greater distance than 'the thickness oi the packing 1S while the pressure of tlie in Howing'watcr lis, first exerted upon the lower section 13 which is yieldingly arranged with respect to the remaining elements of the .plunger ,thereby taking up the vibrationsand preventing what is commonly termedchattering. All upward movement of the Section 13 is thereby cushioned and it will he understood that ,the .bolt head 47 being squared and arran ed Within Athe correspondingly shaped c iamber 16,anyrelative rotation between. the sections 12 and .13 is prevented. The packing 17 -is adapted to cushion the head 47when the .packing 18 has become warnend reduced iin-thickness.

In Fig. 6 the plunger 43 is illustratedpartially in section and employing a 2 part lower section 12-n .13" inplace .ofthe lower section 18 hereto sections being secured to the boit14- in the same manner by an elongated screw 15. The .section r13` is threadedl upon the bolt 14, while Vthe section 13 is secured at the lower endthereof and is provided with a tapered lower face'48'. It will-he understood .that

-when theform .of plunger is employed, as

shown in Fi .-6, .the ball .19.will be omitted as the conica face 48 of the lower section 13". thereofiis adapted to rest upon the valve seat 2 uponV the closing of the valve.

Whatlis claimed as new isz 1. A valve comprising a goblet-shaped casing having un inlet 'lissage in the stem portion thereof and a p urality of relatively small ports through the wall of the cup orton of the same, an extension cerne by the cup portion of said casn Shaving an axial bore, a cage depending om the extension and arrange-d within said cup portionfand. a freely movable cushioned. reciprocating `controllin means for said inlet.

ore described1 the said-two passage arranged within said bore und said valve comprising `goblet-'ahapecl' casing having an inlet passage in the Stem portion thereof and e. plurality of relatively small outlet ports through the wall of the cup ortion of the same, an .extension carried y the cu portion of said ngan axialthe extension and arranged within said cup ortion, a valve, seat member secured in the ottom of said oop -portion extending in wardl of the cage andthavintg a .p e theret Vough in inement wi saldasat passa e, and a. cushioned reciprocating float contro led means for closing said -valve seat passage.

3. y valve comprising a goblet-shaped casing having an inlet passagev inthe stem casing have' ore, a cage depending from.

portion thereof and outlet ports through the wall of the cup portion of the same, an extension carried by the cup portion of said casing and having an axial bore, acage de pending from the extension and arranged within said cup portion, a valve seat member secured in the bottom of said cup portion and having a passage therethrough in alinement with said inlet passage, an annular depending apron carried by said cup portion of the casing forming a chamber between said cup portion and apron with an annular outlet at. the lower end thereof, a sound insulator carried by the inner face of said apron outwardly of the said ports, and a reciprocating controlling means for said valve seat arranged within the bore and said cage.

4. A valve comprising a goblet-shaped casing having an inlet passage in the stem portion thereof and outlet ports through the wall of the cup portion of the same, an extension carried by the cup portion of said casing having an axial bore, a cage depending from the said extension within said cup portion, a valve seat member secured in the bottom of said cup portion extending inwardly of the cage and having a passage therethrough in alinement with said inlet passage, an annular depending apron carried by said cup portion of the casing, forming a chamber between said cup and apron with an annular outlet at the lower end thereof, a sound insulator carried by the inner face of said apron outwardly of the said ports and a shiftable cushioned controlling means for said valve seat arranged within the said bore.

5. A valve comprising a cup casing having an inlet in the bottom thereof and radial outlets through the sides of the same, a tubular extension carried by said casing, a cage depending from said extension, a valve loosely and shiftably arranged within the said cage, a cushioned plunger shiftably arranged within said extension and cage and controlling means for said plunger.

6. A controlling plunger for valves, comprising an upper section having a rectangular chamber in the bottom thereof, a packing at the inner end of said chamber, an intermediate section carried by said upper section, a bolt slidabl arranged through said intermediate section with a squared head positioned within said chamber adjacent said packing, a lower section secured to said bolt having a bottom engaging face and a shock-absorbing washer carried by the bolt between said lower and intermediate sections.

7. A reciprocating valve plunger comprising an upper section, an intermediate section rigidly and removably secured thereto, a lower section shiftably attached to said intermediate section and having a Vbottom engaging face, a r:ushioning member arranged between said intermediate and lower sections, the said intermediate and lower sections being normally separated a greater distance than the thickness of said cushioning member.

8. A plunger member comprisin an upper socketed section, an interme late section removably attached to said upper section, a cushion Within said socket, an attaching member comprising a bolt shiftably carried by said intermediate section, normally spaced from the said cushion, a lower section having an engaging face secured to the said bolt and resilient means upon said bolt between said intermediate and lower sections, the said bolt being adapted for engagement with said cushion upon the reduction in thickness of said resilient member during the wearing of the device.

9. A sound-reducing valve structure comprsing a cup casing having an inlet passage and radial outlet ports, a cylindrical sound insulation means arranged outwardly of said ports, a valve for said inlet passage, a plunger arranged adjacent said valve, the said plunger being formed of loosely connected sections and sound cushioning members between the sections of the plunger.

In testimony whereof we aiix our signatures.
